SPECIFICATION forming part of Letters Patent No, 375,322, dated December 20, 1887.

Application filed June 25, 1887. Serial No. 242,509. (No model.)

To all whom it may concern:

Be it known that I, DANIEL JosEPH HARD- ING, a citizen of the United States, residing at Louisville, in the county o'fJeiferson and State of Kentucky, have invented certain new and useful Improvements in Oar-Couplings; and I do declare the following to be a full, clear,and

exact description of the invention, .such as will enable others skilled in the art to which it appertains to make and use the same, reference'being had to the accompanying drawings,

and to letters or figures of reference marked thereon, which form a partof this specification.

Figurel of the drawings is a representation of this invention and is a vertical section. Fig. 2 is a horizontal section through the end i of the draw-head, showing the recess and slots in the bottom of it. Fig. 3 is a bottom view of the draw-head. Fig. 4 is a front view of the draw-head, the link being in section.

This invention has relation to couplers; and it consists in the construction and novel combination of parts, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the draw-head, and B a link adjusting or lifting lever under the same, pivoted to an arm or hanger, 0, extending downward from the rear'of the draw-head and bifurcated to receive the slotted end of said lever.

D represents the slot in the rear end of the lever, and E is the pivot-pin.

The forward end of the lever is branched and connected to the two liftingstems F,which are laterally placed and extend downward through lateral slots G in the bottom of the draw-head chamber, these slots being at the side of the lower aperture, H, for the coup ling-pin K. The semicircular lifter L is bent in the horizontal plane, and has its convexity in front, as indicated. Its rear ends are bent downward, as shown, to form the two lifter-- stems F. An arc-shaped recess, m, connects the upper ends of the apertures or slots G, and

serves to receive the arc-shaped lifter L when the latter is in its lowest position, so that its face is flush with the floor of the chamber of the draw-head. Thelifter-stems and the branched head of the lever under the draw-head are protected by a guard-lip, S, which depends from the front of the draw-head, as shown. This depending guard affords a defense against obstructions, such as low draw-heads and deadlinks', which would be apt to destroy the efficiency of the lifting devices.

To raise the mouth of the draw-head and provide sufficient room between the upper and lower edges of the mouth of the draw-head, the roof of the chamber of said draw-head (indicated at V) is pitched upward toward the front, as shown.

The lifting-lever is operated by atransverse crank-lever which is connected to the bed or frame of the car and serves not only to operate the lever B to adjust the link, but also when running to raise the drawhead itself. The draw-head usually has vertical play to the extent of two or two and a half inches.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. In combination-with a draw-head having its chamberroof inclined upward and forward and the guardlip, of the lifting-lever and the liftingstems in the rear of the guard-lip, substantially as specified.

2. The combination, with a draw-head having slots on each side of the lower pin-hole, of the rear slotted lifting-lever havingabranched front end, and the arc-shaped lift-er having the lateral stems extending downward through said slots and connected to the front branches of said lever, substantially as specified.

3. The combination, with a draw-head having a central pin-hole, slots on each side of the same, and an arc-shaped recess connecting the upper ends of said slots, of a lifting-lever
